While all miners work from the most recently discovered block (think of it as the "original" block), the selfish mining process begins when a pool of miners discovers a new block and doesn't publish it. The selfish pool then begins working on discovering yet another block, mining from this hidden one. Meanwhile, the rest of the "honest" miners are still wasting resources mining from the original block.

Can you mine FROM a "hidden" block? This makes no sense to me.

Sure, you can mine a block, not publish it, and continue mining. But unless your pool has 51% of the network, the odds are the rest of the network will invalidate the block you are hiding, and then you've just lost a block and have to start over. It does nothing to harm the network, just yourself.

From what I read, the attack requires them to find 2 blocks before anyone else finding the same first one they found.  Easier said than done.  The averages are WAY against it.  You might get away with it once or twice ever, but it's certainly not going to bring down bitcoin.

Funds cleared,

You may now crash in your own time bitcoin. Preferably sooner rather than later.....

What are you hoping for? Wink

I'm hoping for Fibonacci's evil twin, Fibocrashy!

Looks like they are talking about 51% attack and blockchain forking, without actually understanding what they talk about...

No, it's not a 51% attack. But similarly, it does depend on miners doing something that will eventually hurt their own investment.

It's a 26% attack. Not really a big deal tough.

What exactly is this rally running on right now?


Fake volume in china by all the criminals who fled FINCEN registered exchanges.

This bubble will inflate further and burst even louder than the last one.

*bearlogic*


If it inflates more than 350, that's no bubble. That's a miracle. Actually if it stays above 300 is a miracle.

Lol just the fact Bitcoin exists is a miracle, the fact it's above $2. Makes me think there is a God.

I doubt the 'criminals' you say will actually move fiat, so FinCEN is irrelevant..

Yes they will they use HSBC and the like. The fines they pay FinCEN are larger than the Bitcoin market cap.

walsoraj and bears, now you have grounds to predict an imminent crash:


Bitcoin Researchers: You Can Game the System

http://mashable.com/2013/11/04/bitcoin-cornell-researchers/



Selfish miners gonna kill bitcoin , In USD we trust  Wink


How is it that they have no requirement to understand anything in the university concerning the topic they are researching...?

I was wondering if what they said was even possible. I never heard of hiding found blocks and the like.

Yes you can mine on any block created.

But this only makes sense if the pool has 51% of the hash rate, otherwise the public chain will statistically grow longer.

This is also why you wait at least 6 confirmations to consider a transaction valid. A sub 50% pool can statistically mine on an alternate hidden chain for a few blocks from time to time.

In practice no one has done this because it is wasting your mining power and revenue. ...
